Detailed Description

template<class TTransform, class TFixedImage, class TMovingImage>
class itk::LandmarkBasedTransformInitializer< TTransform, TFixedImage, TMovingImage >

LandmarkBasedTransformInitializer is a helper class intended to The class computes the transform that aligns the fixed and moving images given a set of landmarks. The class is templated over the Transform type. The transform computed gives the best fit transform that maps the fixed and moving images in a least squares sense. The indices are taken to correspond, so point 1 in the first set will get mapped close to point 1 in the second set, etc. An equal number of fixed and moving landmarks need to be specified using SetFixedLandmarks() SetMovingLandmarks(). Any number of landmarks may be specified. Call InitializeTransform() to initialize the transform.

Currently, the following transforms are supported by the class: VersorRigid3DTransform Rigid2DTansform

The class is based in part on Hybrid/vtkLandmarkTransform originally implemented in python by David G. Gobbi.

The solution is based on Berthold K. P. Horn (1987), "Closed-form solution of absolute orientation using unit quaternions," http://people.csail.mit.edu/bkph/papers/Absolute_Orientation.pdf
